Stop spending hours fighting your breadboard! With the Dr. Duino Explorer, you’ll save a ton of time on your next Arduino project. Whether you’re a novice or experienced Arduino user, the Explorer offers an array of commonly used sensors and modules with the ability to connect and disconnect what you need at will. It has a novel mechanism for routing digital and analog I/O pins to wherever you need them.
In the previous installment, we discussed the Five Program Steps and how we can use those five steps to organize our thoughts about writing programs. In this article, we’ll discuss the format that the Arduino Integrated Development Environment (IDE) requires for your program to execute in the IDE. We’ll then examine how the IDE allows us to easily organize a program using the Five Program Steps.
An RTOS (Real Time Operating System) is a software component that lets you rapidly switch between different running sections of your code. Think of it as having several loop() functions in an Arduino sketch where they all run at the same time.
Most of us have invested some time in learning those things we want or need to do. Learning how to program is no different, and it can be an extremely satisfying endeavor. Seeing a device respond to code you wrote is, well, intoxicating in a good way. My goal is to create an interest in exploring microcontrollers and encourage you into investing $5 and some of your time into that exploration. I honestly think you'll enjoy the journey.
In addition to making breadboarding easier, the new Dr. Duino Starter Kit can be a useful tool in learning Arduino hardware and software design. Getting into microcontroller development for the first time can be a daunting undertaking and anything that can simplify the process will be welcomed by many. Plus, there are many other possibilities for how this kit can be used.
This project implements a clock/timer device with several handy features other than just a simple alarm. It utilizes a 16-bit PIC, the MPLab Code Configurator, and a serial LCD.
Work areas usually have multiple power strips ganged together and connected to the same outlet. Various devices are connected to these strips, including computers, lights, coffee pots, space heaters, etc. Environmentally conscious persons ask, “How much power does my work area consume?” Safety conscious persons ask, “Am I overloading my circuit?” Calculating the answers requires two basic measurements: the voltage supplied to the circuit, and the amperage consumed by the circuit. Measuring AC voltage and, particularly, amperage with a multimeter is a potentially dangerous diagnostic for laypersons.
Wouldn’t it be nice to have a self-contained volt/amp meter that displays the values on a webpage?
The Parallax Propeller chip is an impressive multi-core microcontroller ... and the Propeller FLiP board makes it even more powerful! See how to integrate these together in your projects.
Want to “paint with light?” This article explains in detail how you can build a low cost (<$100) microprocessor-controlled LED light saber that provides as much or more capabilities than professional light wands.
